Results

The degree of temporal summation of pain after clenching induced by repeated electrical stimulation to the masseter muscle showed statistically significant increases 2 days after the exercise only in the eccentric condition of the preloading exercises but not in the gum chewing condition.
It was demonstrated that pain sensitivity after the low-level clenching could be influenced by the type of the preloading exercise.
